ABOUT THIS GUIDE

Introduction The LANplex 6000 Administration Console User Guide provides all the

information you need to conﬁgure and manage your LANplex system once

it is installed and the system is attached to the network. Prior to using this

guide, you should have already installed and set up your system using the

LANplex 6000 Getting Started guide.

Audience description This guide is intended for the system or network administrator who is

responsible for conﬁguring, using, and managing the LANplex system.

It assumes a working knowledge of local area network (LAN) operations,

and a familiarity with communications protocols that are used on

inter-connected LANs.

If the information in the release notes shipped with this product differs from

the information in this guide, follow the release notes.

Throughout this guide, information that applies to the LANplex

Management Module Plus (LMM+) also applies to the original LANplex

Management Module (LMM).

DMINISTRATION OVERVIEW

This chapter introduces you to LANplex 6000 administration and brieﬂy

describes the switching system parameters that you can conﬁgure.

For information on LANplex Extended Switching functionality refer to the

LANplex 6000 Extended Switching User Guide.

About LANplex

Administration

The LANplex system switching software is installed at the factory in ﬂash

memory on the LANplex Management Module Plus (LMM+). Because this

software boots from ﬂash memory automatically when you power on your

system, the system is immediately ready for use in your network. However,

you may need to conﬁgure certain parameters for the system to operate

effectively in your particular networking environment. Your LANplex system

may contain several different module types, each of which provide certain

types of functionality. A listing of the modules and their conﬁgurable

parameters is provided below:

■ LANplex Management Module Plus (LMM+) — System-level conﬁguration

parameters and management conﬁguration parameters.

■ FDDI Concentrator Module (FCM) — FDDI conﬁguration parameters.

■ Ethernet Switching Module (ESM) — Ethernet, bridging, and routing

conﬁguration parameters.

■ Ethernet/FDDI Switching Module (EFSM) — Ethernet, FDDI, bridging, and

routing conﬁguration parameters.

■ Token RIng Switching Module (TRSM) — Token Ring bridging conﬁguration

parameters.

Unless speciﬁcally referenced by name, the ESM, EFSM, and TRSM are referred

to as “switching modules” in this guide.

1-2 CHAPTER 1: LANPLEX 6000 ADMINISTRATION OVERVIEW

Additionally, when managing your LANplex system, you may want to view

important MAC, port, bridge, and IP statistics. The LANplex 6000

Administration Console allows you to conﬁgure your system and display

these important statistics. For more complete network management, you

can use an external application, such as 3Com’s Transcend Enterprise

Manager.

Conﬁguration

Options

You can conﬁgure the following parameters for your LANplex system from

the Administration Console:

■ System-level (Table 1-1)

■ Management Access (Table 1-2)

■ Ethernet, FDDI, and Token Ring (Table 1-3)

■ Bridging (Table 1-4)

These tables provide a brief description of each parameter, along with the

Administration Console command to access the conﬁguration task quickly.

They also tell you where to look in the documentation for additional

information about conﬁguring the speciﬁc parameter.
